The shovels IQ of the attachment follow in the path of the rubber tired rear wheels 3'! of the tractor B and work the ground so as to close the ditch or channel as created by each wheel in the advancement of the tractor. Qn thelworking of the lever in one direction and the latching thereof, the shovels I9 will be held in an inactive position then by adjusting the said lever 30 in a reverse direction regulates the depth of cut of the shovels l9 when the tractor is advanced and these shovels have been lowered into ground working position. V

The springs 25 function to tension the shovels l9 and also will absorb shocks and vibrations incident to the travel of the tractor when the shovels I9 are in working position.

What is claimed is:

An attachment for a wheeled tractor having a chassis frame, comprising bearings fixed to the aft portion of said frame, a shaft disposed transversely of the frame and fitting said bearings, said shaft being of square formation in cross section, hanger clamps including superposed plates having registering V-shaped seats in their inner faces for engaging said shaft, arms bolted between the plates of said hanger clamps and swingably adjustable in a lateral direction, ground working elements adjustably fitting said arms, means tensioning the said shaft for urging the same in a direction for the sinking of the ground working elements in soil, a throw lever pivoted to the chassis frame, a keeper for said throw lever, an arm fixed to the said shaft and having a clearance, a coupling shank pivoted to the lever and received in said clearance, an adjustable pin fitting said coupling shank for abutment of the last-mentioned arm therewith, and a spring coacting with the shank and urging the last-mentioned arm in contacting relation with the pin.
